Bird strike was also a major issue for growers.
“They finish in the grapevines, and then they turn to the olive trees, especially in Canterbury and Wairarapa,” Glover said.
“Starlings just flock and can destroy entire groves overnight, or actually during a day.
“And because of the drought, there’s not the other bugs and things to be eaten.
“They’ve picked on us.”
The disappointment is palpable when growers were really hoping to step in and provide oil in an under-supplied market because Spain, the world’s largest producer of olive oil, has had two bad harvests in a row due to very dry weather.
With the lower yields comes a huge drop in income for some growers and Glover believed some may leave the industry.
“Costs have gone up. Labour has gone up, importing everything else we use has gone up. So it is huge.
“There’ll be a lot of groves just not viable. That’s just the reality of it.
“They’re not going to keep growing, because to increase the volume, the growth (trees) needs to be maintained.
“If people are going and looking for employment elsewhere to supplement incomes, they don’t have the time and effort to put into growth.”
The one bright spot, Glover said, was the flavour was back again this year after several wet years when the fruit did not produce such an intense taste.
“Taste is definitely trending up towards to what we expect if you were buying New Zealand.”
